We are seeking a Software QA Engineer to take ownership of quality assurance across our product suite, with a primary focus on Cim
360.cloud, our next-generation multi-tenant cloud manufacturing platform. Cim
360 is still in active development (pre-release), so the role will be highly hands‑on, iterative, and embedded closely with the development team.

You will help define and shape how QA is done for Cim
360, including tools, processes, and automation, while also supporting testing for our mature desktop products Cim
200 and Cim
50. These require structured testing on a more predictable schedule and make up a smaller percentage of the role.

This is an opportunity to build modern QA practice within a growing engineering team and ensure reliability across cloud and on‑premise products.
